Efficacy of intraoperative indocyanine green videoangiography (ICG-VA) and FLOW 800 in the surgical management of intracranial aneurysms: a systematic review and meta-analysis

The combined use of ICG-VA and FLOW 800 enhances the intraoperative detection of misclipping, residual aneurysm, and flow disturbances not evident with ICG-VA alone. These findings support its role as a complementary intraoperative tool. However, due to limited validation against angiographic standards, it should not replace DSA. Further prospective studies are warranted to confirm its clinical utility and encourage broader adoption in neurosurgical practice.

Abstract

The combined use of ICG-VA and FLOW 800 enhances the intraoperative detection of misclipping, residual aneurysm, and flow disturbances not evident with ICG-VA alone. These findings support its role as a complementary intraoperative tool. However, due to limited validation against angiographic standards, it should not replace DSA. Further prospective studies are warranted to confirm its clinical utility and encourage broader adoption in neurosurgical practice.
